Setting up the amplifier as one in and four out means there is one input channel through which the audio signal can be fed into the amplifier, and four output channels through which the audio signal can be distributed to four speakers or sound systems.

On stage, it is usually necessary to distribute audio signals to multiple speakers or sound systems. Setting the amplifier to one input and four outputs allows for high-quality audio signals to be simultaneously provided to multiple speakers, ensuring that every audience member can hear clear and balanced sound effects.

With a 1-in-4-out configuration, audio signals can easily be routed to different speaker systems. This flexibility allows live engineers or audio professionals to adjust audio outputs and achieve custom mixing to meet specific sound system requirements.

How does a Sinbosen amplifier insert a signal and play the same signal on all four channels?
